The London Underground is one of the most extensive in the world and is known as Tube or Underground, although the first name is usually more common.
This metro network has 11 different lines that are distinguished by colors and that encompass the 9 circular areas in which the city is divided. Basically, when the tourist comes to London new to do not understand very well the concept of metro areas but it is as simple as that zone 1 is the center of the city and the following are moving away in a circular way towards the outskirts.
For this reason, it is very important to know how to locate on the map where our destination stop is located in order to know which area we are going to and to get the right ticket. Remember that in London do not walk around with nonsense and if you get caught getting off in zone 4 with a ticket for zones 1-2 you will have to pay a fine.
The easiest thing for the tourist who is going to stay in the city for more than 3 days is to buy an Oyster card or a travel card for a week. Thus, the cost of each ticket will be cheaper and you will not have to worry about how many times you enter and leave the metro. Enjoy the city without worrying about transportation!
If on the contrary you decide to buy individual standard tickets you should know that the prices are higher than with any of the previous cards. For example, the rate for zones 1-3 is more than 4 pounds and the rate for zones 1-6 is 5 pounds.
Since there are so many different lines and areas, it is best to take a small pocket meter plane that you will get at any of the metro stations in the city.
As a general rule, the frequency of the meters is 2 or 3 minutes but what you should keep in mind is that at 12 o'clock at night the meter closes and stops being available as a means of transport. In any case, some lines usually extend the time until 1 at night but it is in the most exceptional cases.
Regarding the opening time you are lucky because from 5 in the morning you can start your London adventure.
On the other hand, you should know that during the weekends there is always some area of some line cut for maintenance. This can negatively influence your plans so it is better that you inform yourself on the posters of the stations or on the official website itself in which they always advise in advance. The circular line is one of the most damaged most of the time.
In short, the London underground is the fastest transport you can use to move from one place to another and although it may seem very complicated to use, it is a matter of adapting a bit and trying to understand the configuration of the network.
